Problem of practice
A conventional treatment of "coefficient of friction" that emphasizes looking up values in a table is unmotivated and even dishonest. The reliably proportional relationship between friction and normal force provides an opportunity for students to develop a model for this relationship through student-designed experiment.
Solution
Use inquiry to develop a graphical and algebraic model of friction that emphasizes the specific experimental conditions. Furthermore, situations to which the model may NOT apply can be examined to provide a more robust understanding of the model.

Through forming and testing conjectures about a "black box" device, and reflecting on this process, students can get an idea for what kinds of activities you will have them do in your class for the rest of the year.

A single replacement reaction is used to show how to link observable changes to particle behavior duirng chemical reactions. Students piece together a particle "story" based on observable changes and their knowledge on atoms, electrons and ions.

Students make an observation that cannot be explained by a previously very successful particle model of light. This leads to interesting discussions about the nature of science in general, and about an alternative (wave) model of light.

I describe three key elements to successful implementation of APEX as a credit recovery option for students:
1) Having highly accessible and hands on approach to holding students accountable.
2) Setting up self-reporting feedback structures using A

Two interlinked, discursive learning cycles, the modeling cycle and the design cycle, are proposed as a template for inquiry-based curriculum design. An example is provided of a year-long curriculum centered on modeling electricity and magnetism.

Use screencasts and a class website to create a flipped classroom where instruction of content is completed outside of the classroom and class time is used for more engaging activities and skill building.

Students are encouraged to explore their own passions, and develop their own areas of interest. This keeps student in the middle of their own inquiries. We also nurture &guide students in how to comment for each other to build authentic conversation.
